Abstract - USGS
An evaluator should note that molybdenum mills have a higher reagent cost than most base metal flotation plants (i.e., copper, lead, or zinc). The model is valid for mill feed rates of 500 to 40,000 st/d. Typical recovery rates for base metal one-product flotation plants for copper, molybdenum, lead, or zinc are 90%.

Waste Production and Utilization in the Metal Extraction Industry
Spirals: The spiral concentrator is one of the most common and cost-effective gravity concentrators and has found wide spread application in the processing of minerals such as coal and chromite ores. It uses a flowing film principle based on the size and specific gravity difference present in a suite of minerals.
